Answer:
b=29.74
Step-by-step explanation:
tan b=opposite/adjacent
tan b= 4/7
b=29.74
Area of a triangle is = 0.5bh
if the height (h) is 4 less than base (b) then h = b - 4
48 = 0.5(b)(b - 4)
48/0.5 = b² - 4b
96 = b² - 4b
b² - 4b - 96 = 0
(b + 8)(b - 12) = 0
b must be either -8 or 12
since a distance can't be negative that means
the base is 12
Answer:
12 times
Step-by-step explanation:
x is the number of times she has to walk dogs multiplied by 5 dollars she gets each time plus the 25 she started with all equal to 83 because that's how much she needs
5x + 25 = 83
-25 -25
5x = 58
5x/5 = 58/5
x = 11.6
can't walk the dog a 6th of a time so rounded to the nearest while number ti get 12
she has to walk dogs approximately 12 times
Answer:
Commutative Property
Step-by-step explanation:
It looks like Associative property which is when you change the GROUP, but actually it’s commutative because it didn’t change any numbers in the group, just the order of where they were.
Associative: (25 + 19) + 15 = (15 + 19) + 25
Commutative: (25 + 19) + 15 = (19 + 25) + 15
It didn’t change the numbers, only the order. Therefore, it would be commutative property
